Co‑cyprindiol and Epiduo gel

Co-cyprindiol Tablets&Epiduo Gel — 45 acne treatment

An effective combination for treating hormonal acne. A contraceptive pill with a topical gel that contains both benzoyl peroxide and adapalene to target breakouts.

  • Co‑cyprindiol helps prevent acne and protects against pregnancy 

  • Epiduo gel exfoliates, breaks down spots and calms inflammation

  • Suitable for women only

What are co‑cyprindiol and Epiduo gel?

If you’re a woman and skin creams or antibiotic tablets haven’t cleared up your acne, your doctor or clinician may prescribe co-cyprindiol (also branded as Dianette). Co-cyprindiol helps reduce the amount of oil (sebum) your skin produces, which feeds acne. It also doubles up as a reliable, regular contraceptive.

Epiduo gel contains two active ingredients. The benzoyl peroxide in it works to kill bacteria and control oil production. This can reduce redness, swelling and help prevent breakouts. It also has a topical retinoid (exfoliant) called adapalene, to help remove dead skin and reduce inflammation.

When prescribed together, co‑cyprindiol and Epiduo gel work to treat both the hormonal trigger of acne and visible spots. Together they make an effective acne treatment combination, which can also be prescribed as Epiduo gel and Dianette or Clairette and Epiduo gel.

How do I take co‑cyprindiol and apply Epiduo gel?

Co‑cyprindiol 

Take one tablet at the same time each day for 21 days, then pause for 7 days. After this 7-day break you repeat subsequent courses of 21 days on, 7 days off.

Starting co‑cyprindiol on the first day of your period gives you immediate contraceptive protection.

Epiduo gel

  • Before bed, Gently wash your face, rinse and pat dry.

  • Smooth a thin layer of Epiduo gel onto your clean, dry skin.

  • Let the gel dry fully before using moisturiser or putting on make‑up, and use a non‑oily sunscreen each morning (SPF 30+).

Epiduo gel may irritate your eyes and the benzoyl peroxide in it can bleach towels, clothing, bedding or even your hair. So always wash your hands after applying it.

How does the combination of co‑cyprindiol and Epiduo gel work?

Acne in women is often driven by androgens (male hormones) like testosterone, which increase oil production in your skin.

Co-cyprindiol contains ethinylestradiol (a type of oestrogen hormone) and cyproterone (an anti-androgen), so it can:

  • Block androgens, making your skin less oily (and shiny). This means pores aren’t as likely to get clogged (which can cause new breakouts).

  • Targeting the hormonal cause of acne also means co-cyprindiol can help with other conditions related to excess androgens like polycystic ovary syndrome or hirsutism (excessive female hair growth).

Epiduo gel contains two active ingredients: 

  • Benzoyl peroxide is antibacterial and also has an anti-inflammatory effect. This can reduce redness, swelling and help prevent breakouts

  • Adapalene is a topical retinoid. Its main actions are to normalise skin cell development, prevent pores from being blocked and promote skin renewal.

Will co‑cyprindiol and Epiduo gel be an effective treatment?

This pairing works best for women whose acne features pustules (small red spots with a white tip). By tackling both the hormonal trigger and the surface spots, it improves the cause and the appearance of acne.

Are there any side effects from co‑cyprindiol and Epiduo gel?

Co‑cyprindiol 

As a combined oral contraceptive, the possible side effects of co‑cyprindiol are similar to other contraceptive pills. Though not every woman gets them, common side effects include:

  • Headaches

  • Mild sickness (nausea)

  • Sore breasts tenderness or breast pain

  • Mood swings or low mood

  • Changes in sex drive (libido)

  • Slight weight gain or sometimes weight loss

There are also some rare but more serious risks of side effects from co‑cyprindiol that you should be mindful of.

  • All combined pills carry a small increased risk of blood clots.

  • Co‑cyprindiol has been associated with a slightly increased risk of breast cancer if used for many years.

If you have any warning signs like unexplained calf pain, chest pain, or major mood depression while taking co‑cyprindiol, seek medical advice straight away. 

Epiduo gel 

As it combines two active ingredients, when you use Epiduo gel you could get side effects from adapalene (a retinoid) or benzoyl peroxide. Common side effects include dry or peeling skin, redness, mild burning or stinging and Itching or irritation.

The benzoyl peroxide in Epiduo gel can also increase your sensitivity to sunlight. So, it’s even more important to protect yourself. Apply a non oily, fragrance-free sunscreen daily (SPF 50), try to stay out of the sun when it’s most intense and avoid sun beds. 

Full details on use and safety are in the co-cyprindiol and Epiduo gel patient information leaflets.

Frequently asked questions

Co‑cyprindiol and Epiduo gel are not recommended if you’re pregnant, breastfeeding or trying for a baby. Ask your doctor or our clinicians about safer alternatives.

Taking some medicines at the same time as co‑cyprindiol can make it less effective. In particular: 

  • The antibiotics rifampicin and rifabutin (often used to treat illnesses like tuberculosis and meningitis) can reduce the effectiveness of the combined pill. So you may have to use additional contraception like condoms.

  • Medicines called enzyme inducers. This includes a number of epilepsy drugs, antiretroviral medicines used to treat HIV, and St John's wort (a herbal remedy).

Avoid using Epiduo gel alongside products that contain erythromycin, tretinoin, isotretinoin or tazarotene. Also steer clear of using strong exfoliants or alcohol‑rich toners at the same time.

Always let your doctor or our clinicians know about medications and supplements you’re taking or using, so they can prescribe treatments safely for you.

If  co‑cyprindiol and Epiduo gel aren’t suitable for you, there are alternatives:

  • Other topical treatments like azelaic acid. 

  • Other hormonal options for women such as low‑dose combined pills or spironolactone.

  • Oral antibiotics combined with topical treatments.

  • Lifestyle tweaks like a balanced diet, gentle skincare and avoiding heavy make‑up.

  • A dermatologist can recommend isotretinoin for severe, stubborn acne.

  • Light therapy and chemical peels may be more effective than medication in some cases.

  • Getting stubborn whiteheads, blackheads or cysts removed using special tools could improve how your skin looks short term, but can also scar it.

Your GP or our clinicians can advise you on the best acne treatment for clearer, healthier looking skin.
